Also the clones will be showing preflowering already so you can flower them small.
If you want you can take clones from a mother plant and keep adding a clone every week or so- this way you get a continuous harvest.

If you are growing from seed the plants will likely get a bit big for a SOG grow.

If you don't want to mess around with cloning then consider less plants- maybe 4 in that space. With some Low Stress Training (lst) you can get a nice even canopy so the plants can use all the light.

Here's a pic of a SOG using a screen to keep the canopy even, sometimes called scrog.
